I haven't yet had someone give me a legit excuse not to use cash. I know about the online banks and some peoples inability to get cash quick, and I would work with those people. I did have someone drive to two different branches one time to get enough cash, but we both agreed that was a minor inconvenience.
Typically, people who have wanted to pay me with a check have wanted the game that day. There was a local guy trying to buy a $3,300 game. My ad said cash only, he wanted to give me a certified check and take the game. He wouldn't budge, so I didn't sell him the game. He admitted he could pay in cash but wouldn't, I couldn't figure out why so I sold it to someone else. Very frustrating as he wasted a lot of my time as my ad did say cash only. He should have asked first before coming over and looking the game over for an hour and a half, since there was no chance of a deal.
I've held games for people several times, sometimes for weeks, but the game has always been payed in full or they were someone I've dealt with before. If someone wanted to buy a game and they had an online bank, I'd take what they could get today as a non refundable deposit and give them a couple weeks. Online bank or not, I think 14 days is probably enough time to secure the funds.
There are plenty of honest good people trying to pay with checks, and there are also plenty of terrible people out there trying to pay with checks. I'd rather just avoid it all.
That's my two cents.

You want to buy my machine, I'll take a check or cash I don't care, however the check will have to clear first.
Quoted from Noahs_Arcade:
True, but not entirely. For example, I use an online bank. I am limited to daily withdrawals of $500, or I can call to have it increased to $1,000 for three business days. It would be a huge hassle for me to buy a TRON LE with cash.
